Filter by:RATIONALE: Giving chemotherapy drugs, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer.
This phase I trial is studying the side effects and best dose of lenalidomide in treating young patients with relapsed or refractory solid tumors or myelodysplastic syndromes. Lenalidomide may stop the growth of solid tumors or myelodysplastic syndromes by blocking blood flow to the cancer. It may also stimulate the immune system in different ways and stop cancer cells from growing.
This phase I/II trial studies whether stopping cyclosporine before mycophenolate mofetil is better at reducing the risk of life-threatening graft-versus-host disease (GVHD) than the previous approach where mycophenolate mofetil was stopped before cyclosporine. The other reason this study is being done because at the present time there are no curative therapies known outside of stem cell transplantation for these types of cancer. Because of age or underlying health status, patients may have a higher likelihood of experiencing harm from a conventional blood stem cell transplant. This study tests whether this new blood stem cell transplant method can be made safer by changing the order and length of time that immune suppressing drugs are given after transplant.
This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.
Phase II trial to study the effectiveness of thalidomide in treating patients who have myelodysplastic syndrome. Thalidomide may improve the immune system's ability to fight myelodysplastic syndrome
Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Phase I trial to study the effectiveness of bryostatin 1 combined with sargramostim in treating patients who have refractory myeloid cancer
This phase I trial studies the side effects and best dose of tipifarnib in treating patients with myelodysplastic syndromes. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Randomized phase III trial to compare the effectiveness of different chemotherapy regimens with or without bone marrow transplantation in treating children who have acute myelogenous leukemia or myelodysplastic syndrome. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known which treatment regimen is more effective for acute myelogenous leukemia or myelodysplastic syndrome
